Whereby, driven runner 331 and 332 turns explicitly with rubber rollers 261 and 262 respectivelyMoving. Driven runner 331 and 332 is by molded formation, and all has and apply with fluororesinSuperficial layer.
Fig. 5 is the chart that the relation between moisture content and the adhesion strength of envelope P is shown. FromThis chart understands, along with the moisture content of envelope P increases, with respect to the main body of envelope PThe adhesion strength of Pa increases. This is because in the case of the moisture content of envelope P is large, a large amount ofSteam produces in the time that envelope P is heated at photographic fixing pressing part 22 places of fixing device 129,Therefore the adhesive Pd that, imposes on the lid Pb of envelope P easily dissolves.
Fig. 6 shows the inclined angle alpha (figure with respect to rubber rollers 261 at driven runner 331The tabulation of relation 4B) and between driven runner 331 and the contact width of rubber rollers 261. WhenWhen the inclination angle of driven runner 331 is 0 °, between driven runner 331 and rubber rollers 261Contact width is 8mm, and in the time that driven runner 331 is inclined to the inclination angle with 4 °, connectsTouch narrowed width to 1mm. Understand from this fact, along with driven runner 331 little by little tilts,Become narrower with respect to the contact width of rubber rollers 261.
Fig. 7 shows the current process of the envelope P transfer roller pair of working as the moisture content with 5%Within 35 o'clock, transfer roller is between 35 contact widths with respect to envelope P and the adhesion strength of envelope PThe chart of relation. In the time that contact width is 8mm, the adhesion strength of envelope is 100cN, andIn the time that contact width is reduced to 1mm, the adhesion strength of envelope becomes 0cN, and lid PbBe not easy to adhere to main body Pa. Understand from this fact, along with transfer roller is to 35 contactWidth reduces, and the adhesion strength of envelope P reduces, and lid Pb is not easy to adhere to masterBody Pa.
In Fig. 1 to Fig. 7, envelope P treats the surperficial Pe(Fig. 3 B with address in the above)Under the state pointing to towards photosensitive drums 121, deliver to photosensitive drums 121 and transfer printing charging device 125 itBetween, thus the toner image of address is transferred on envelope P. Then, envelope P gives and determinesImage device 129(Fig. 2), treat to be subject to film unit 20 with the surperficial Pe of address above to makeHeating, thus the toner image T photographic fixing of address is treated to the surperficial Pe with address to aboveOn. After this, envelope P gives transfer roller to 35.
In Fig. 4 A and Fig. 4 B, give the main body Pa of transfer roller to 35 envelope P and mouthfulA part of lid Pb is pressed together between rubber rollers 261 and the driven runner 331 of inclination, andAnd a part of main body Pa is pressed together between rubber rollers 262 and driven runner 332 to be passedSend.
Now, envelope P the lid Pb of envelope P and a part of main body Pa by tilt fromThe outer surface 331a of moving runner 331 is at power F1(Fig. 4 B) under with the turning of rubber rollers 261Part 261b transmits under the state of rubber rollers 261 bendings as fulcrum. Not do not tilt fromMoving runner 332 is outside being pressed together on the main body Pa of envelope P together with relative rubber rollers 262Between perimeter surface 332a and 262a time, rotate, to transmit envelope P.
Therefore, main body Pa is being pressed together on same between rubber rollers 261 and driven runner 331Time by the rotation of rubber rollers 261 and driven runner 331 and be pressed together on rubber rollers 262And between driven runner 332 time by the rotation of rubber rollers 262 and driven runner 332Transmit. But lid Pb is being pressed together between rubber rollers 261 and driven runner 331Only transmit by the rotation of rubber rollers 261 and driven runner 331 simultaneously.
Therefore, do with the corner part 261b of rubber rollers 261 because of lid Pb at lid PbFor fulcrum bending and due to hardness and the own wt and main body Pa of lid towards rubber rollers 261Under the state separating, lid Pb is transmitted. Thereby lid Pb is not easy to adhere to main bodyPa。
In the time that lid Pb separates with main body Pa, be formed with for allow from main body Pa produceThe space that steam is escaped, and between main body Pa and lid Pb, do not have steam to build up. CauseAnd, can prevent that adhesive Pd from dissolving and preventing that lid Pb from adhering to main body Pa.
Even when in the situation of transfer roller lid Pb shake during to 35 transmission envelope, inclination fromMoving runner 331 tilts lid Pb, and can suppress thus the shake of lid and realize level and smoothTransmit.
Envelope P presses the corner part 261b of rubber rollers 261 by driven runner 331. Therefore,Contact width between driven runner 331 and the corner part 261b of rubber rollers 261 is almostZero. Therefore, as shown in Figure 7, lid Pb does not almost have adhesion strength, and is difficult to glueBe attached to main body Pa.
The turning of the intermediate member contact rubber rollers 261 of the outer surface 331a of driven runner 331Part 261b, and outwards outstanding along the direction of principal axis of rubber rollers. Therefore, can be by havingOutstanding length L 1(Fig. 4 B) part increase lid and body portion from possibility.
In Fig. 7, contact width minimum is about 1mm. This is because the turning of rubber rollers 261Part 261b is subject to that driven runner 331 pressurizes and flexibly distortion and slightly flattening. This slightlyEven if the part flattening makes in the time that envelope P presses the corner part 261b of rubber rollers 261 alsoCan also can transmit envelope P.
As shown in Figure 4 A, transfer roller to 35 in, the only driven runner 331 in a sideTilt. But, as the transfer roller shown in Fig. 8 to 235, at two of driven voller 233The driven runner 331 of end can tilt identical along direction separated from one another with 332Angle α. And in this case, outer surface 331a and the 332a of driven runner 331 and 332Intermediate member contact respectively corner part (marginal portion) 261b of rubber rollers 261 and 262And 262b. The corner part 262b of rubber rollers 262 with right angle be formed on rubber rollers 262 outsideBetween perimeter surface 262a and end surfaces 262c. And, the corner part 262b of rubber rollers 262Pressurize and be flexibly out of shape and slightly flatten by driven runner 332.
In the situation that driven runner 331 and 332 all tilts, no matter as institute in Fig. 4 A and 8In the time that envelope P transmits, which side lid Pb points to with showing, can be by lid Pb and main bodyPa separates, and can prevent that lid Pb from adhering to main body Pa.
The transfer roller shown in Fig. 9 A to 335 in, rubber rollers 361 Hes of driven roller 326362 marginal portion is respectively tapered portion 361b and 362b. The tapered portion 361b of rubber rollersTilt to be formed on the outer surface of rubber rollers by the direction along identical with driven runner 331Between 361a and end surfaces 361c. The tapered portion 362b of rubber rollers is by along turning with drivenTake turns 332 identical directions to tilt and be formed on outer surface 362a and the end surfaces of rubber rollersBetween 362c. Inclining of the inclination of tapered portion 361b and 362b and driven runner 331 and 332Monoclinic phase is same or basic identical. It is that 15mm and width are that rubber rollers 361 and 362 respectively has diameterThe shape of 10mm, and turning is cut to form tapered portion 361b and 362b.
The tapered portion 361b of rubber rollers and 362b respectively with driven runner 331 and 332 outsideThe intermediate member of perimeter surface 331a and 332a contacts. Driven runner 331 and 332 respectively hasThe diameter of 15mm and the width of 10mm.
In the time that the marginal portion of rubber rollers 361 and 362 is respectively tapered portion 361b and 362b,Even, under long-term use, the marginal portion of rubber rollers is also not easy wearing and tearing and distortion, andEnvelope can transmit for a long time under stable state.
As shown in Fig. 9 B, at end surfaces 331c and the outer surface 331a of driven runner 331Between corner part 331b can be positioned at end surfaces 361c and the cone against rubber rollers 361The position of corner part 361d between shape part 361b. In addition, as institute in Figure 10The transfer roller showing is to 535, do not have tapered portion rubber rollers 261 corner part 261b and fromThe corner part 331b of moving runner 331 can abut against each other. Although not shown, with figure9B similarly, the corner part between end surfaces 332c and the outer surface of driven runner 332Dividing also can be against the corner part between the end surfaces 362c of rubber rollers 362 and outer surface.Transfer roller is similar with the driven voller 233 shown in Fig. 8 to 335 driven voller 233, and because ofThis, the description thereof will be omitted.
